1.父枚举NoticeTypeEnum

package com.messageService.enums;
    
    import java.util.Arrays;
    import java.util.List;
    
    public enum NoticeTypeEnum {
    
    	SYSTEM(1,"系统通知") {
    		@Override
    		public List<MessageTypeEnum> getMessageTypes() {
    			return Arrays.asList(MessageTypeEnum.ORDER,MessageTypeEnum.REFUND,MessageTypeEnum.AFTERSALE,MessageTypeEnum.COUPON);
    		}
    	},
    	INTERACTION(2,"互动通知") {
    		@Override
    		public List<MessageTypeEnum> getMessageTypes() {
    			return Arrays.asList(MessageTypeEnum.COMMENT,MessageTypeEnum.LIKE,MessageTypeEnum.REPLY);
    		}
    	},
    	DELIVER(3, "物流通知") {
    		@Override
    		public List<MessageTypeEnum> getMessageTypes() {
    			return Arrays.asList(MessageTypeEnum.SHIPMENTS,MessageTypeEnum.SIGNFOR);
    		}
    	},
    	ACTIVITY(4, "活动通知") {
    		@Override
    		public List<MessageTypeEnum> getMessageTypes() {
    			return Arrays.asList(MessageTypeEnum.ACTIVITY);
    		}
    	};
    	
    	private NoticeTypeEnum(Integer code, String remark) {
    		this.code = code;
    		this.remark = remark;
    	}
    	
    	
    	private Integer code;
    	private String remark;
    	public Integer getCode() {
    		return code;
    	}
    	public void setCode(Integer code) {
    		this.code = code;
    	}
    	public String getRemark() {
    		return remark;
    	}
    	public void setRemark(String remark) {
    		this.remark = remark;
    	}
    	
    	public abstract List<MessageTypeEnum> getMessageTypes();
    }

2.子枚举MessageTypeEnum

package com.messageService.enums;
    
    public enum MessageTypeEnum {
    
    	ORDER(1, "订单提醒"),
    	REFUND(2, "退款提醒"),
    	AFTERSALE(4, "售后提醒"), 
    	COUPON(5, "优惠券提醒"), 
    	ACTIVITY(6, "活动通知"),
    	COMMENT(7, "评论通知"),
    	REPLY(8, "回复通知"),
    	LIKE(9, "点赞通知"),
    	SHIPMENTS(10, "发货通知"),
    	SIGNFOR(11, "签收通知");
    	
    	private Integer code;
    	private String remark;
    	
    	private MessageTypeEnum(Integer code, String remark) {
    		this.code = code;
    		this.remark = remark;
    	}
    	public Integer getCode() {
    		return code;
    	}
    	public void setCode(Integer code) {
    		this.code = code;
    	}
    	public String getRemark() {
    		return remark;
    	}
    	public void setRemark(String remark) {
    		this.remark = remark;
    	}
    }
